Abstract: A DRM technique involves packaging an advertisement using a data structure that encapsulates a number of advertising segments along with signed information, such as a table of hashes, associated with some of the advertising segments. In one scenario, the data structure and the signed information are separately protected using public key and/or digital signature cryptographic schemes. The advertisement is delivered to a user of a consumer electronic device (CED) separately from delivery of a digital license, which governs user consumption of the advertisement. The digital license includes keys used in connection with the cryptographic scheme, and references a condition to be satisfied with respect to consumption of the advertisement. As advertising segments are verified and consumed by the user/CED, information is recorded and used to determine whether the license condition was satisfied. Satisfaction of the license condition may result in access to program content or additional licenses.

Abstract: This document describes tools capable of enabling cloud-based movable-component binding. The tools, in some embodiments, bind protected media content to a movable component in a mobile computing device in a cryptographically secure manner without requiring the movable component to perform a complex cryptographic function. By so doing the mobile computing device may request access to content and receive permission to use the content quickly and in a cryptographically robust way.

Abstract: Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.

Abstract: In one or more embodiments, a license associated with a first piece of content can grant rights with respect to a second and/or additional pieces of content. That is, language that is included in a first license can express a policy that is interpreted by a client-side device. This policy can establish rights with respect to additional pieces of content. Accordingly, policy enforcement with respect to licensed content can take place on the client-side device and can establish how different content is to be played relative to one another.
Abstract translation: 在一个或多个实施例中，与第一内容相关联的许可证可以授予关于第二和/或附加的内容的权限。 也就是说，包含在第一个许可证中的语言可以表示由客户端设备解释的策略。 这项政策可以就额外的内容建立权利。 因此，关于许可内容的策略执行可以在客户端设备上进行，并且可以确定如何相对于彼此进行不同的内容的播放。

Abstract: Systems, methods, and/or techniques (“tools”) for binding content licenses to portable storage devices are described. In connection with binding the content licenses to the portable storage devices (“stores”), a host may perform authentication protocols that include generating a nonce, sending the nonce to a store, and receiving a session key from the store, with the session key being generated using the nonce. The store may perform authentication protocols that include receiving the nonce from the host, generating a random session key based on the nonce, and sending the session key to the host.

Abstract: Techniques enable creation of a preview license for digital content. In some instances, the preview license indicates that it allows a content-consuming device to consume less than all of the content. This preview license may create a list specifying multiple portions of the digital content that the content-consuming device may consume. These techniques may also present to a device user an offer to purchase rights to consume all of the digital content after consumption of the preview-licensed portion(s). In other instances, a content server may embed the preview license into a content package that contains the digital content, allowing the server to distribute the package to multiple devices. In still other instances, the preview license may be bound to a domain rather than to individual devices. This allows member devices to share the digital content and the preview license, such that each member device may enjoy the preview experience.

Abstract: The anonymity of a user at a client computer may be preserved when authenticating with an on-line service or content provider through the use of an anonymous and verifiable (i.e., “blind”) certificate set that is created by a certificate authority from a fixed-size set of PKI key pairs. The certificate authority randomly selects a subset of PKI key pairs to generate the blind certificate set where each certificate in the set includes a respective public key from the PKI key pair subset. The certificate authority also sends the private keys from the PKI key pair subset to the user. During authentication, the client computer is configured to randomly select a subset of one or more certificates from the set to present to the provider. The provider will encrypt content using the public keys in the subset of certificates and the client will decrypt the content with the corresponding private keys.
